Can I Redirect/Mapa USB port via RDP (or by any other method)

[nanobit]

I am running a remote, unattended server with Win Server 2003 Standard . This server is connected via a VPN over the Internet to a local system running Windows XP. If I want to require a local user on the Windows XP machine to authenticate on the remote server using a USB token (a type of security device, like an RSA SecureID token), I will need to redirect/map a USB port on the remote server to a USB port on the local Win XP system. Does anyone know how I can do this? Can I do this via RDP? If so, how?

Note that this token is not a storage device. Therefore, it does not use a file system like used in flash drives or USB hard drives. However, it does use Windows drivers.

Thanks.
